Barite Powder for Paper
Barite Powder for Paper
Product Overview
Our Barite Powder for Paper is a high-quality functional filler designed specifically for paper manufacturing applications. It enhances paper performance by improving brightness, smoothness, and overall printing quality while reducing production costs.
Product Characteristics
- Superfine particle size with narrow and uniform distribution
- High purity with minimal impurities
- High whiteness for superior paper brightness
- Excellent dispersibility in paper pulp systems
- Low tendency to agglomerate for stable processing performance
Product Properties
Barite powder is a chemically stable, non-toxic, white inorganic powder. It is insoluble in water and resistant to most acids under normal conditions. When heated with carbon, it can be reduced to barium sulfide.
As a high-whiteness functional filler, it helps reduce material consumption and production costs while maintaining product quality. In paper manufacturing, it improves surface smoothness, fineness, and printability. It also helps extend the service life of paper machine wire mesh by reducing wear.
Application
Barite Powder for Paper is widely used in paper production as a high-performance filler to improve optical properties, surface quality, and operational efficiency.
